At the time of building, it was estimated that it would take two years to fill by natural rainfall and melting snow, but the flood of March 1938 in this section filled the Lake in 11 days. This is the cause of the trees still being in the Lake at the time this picture was made. They have since been removed. Photo by Roy E. Rose -- 1938"
